ST "ll DOOR-HANGING DEVICE.,

Application filed March 26, 1915.

To all whom t may concern.'

Be it known that I, FREDERICK A. LEsTER, a citizen of the United States, residing at Chicago, in the county of Cook and State of lllinois, have invented a certain new and useful Door-Hanging Device, of which the following is a specification, reference being had to the accompanying drawings, forming a part hereof.

This present invention relates generally to the class of door hangers, and has reference more particularly to that type of door hanging device applicable to railway freight car doors designed for lateral movement into and out of the doorway opening, such as is shown in my co-pending application for car door, Serial Number 874,640.

One of the principal objects of my invention is the provision of an improved form of such door hanging device embodying a plurality of roller devices or anti-friction elements carried by the door and door track and arranged with reference to each other so as to permit normal longitudinal travel f the door to a position clear of the doorway opening and a lateral movement thereof into and out of the said opening.

A further object is to produce a simple and efficient device of this character that can be readily made and easily applied to the car at a minimum cost.

rlhese, together with such other objects as may hereinafter appear or are incident to my invention, I attain by means of the construe.- tion illustrated in preferred form, where- 111:-

Figure 1 represents a front elevation of a fragmentary portion of the car body and door illustrating the application of my improved device thereto, and showing the door in its closed position.

Figure 2 is a sectional view of the device taken on the line 2 2 of Figure 1.

Figure 3 is a similar section showing the device with the door moved out of the door opening in readiness for longitudinal movement of the ear to clear the doorway opening; and E Figure 4 is a cross-section taken on the line 4-4 of Figure 2.

Referring to the drawings, the numeral 5 indicates the car body, 6 the door, 7 the door-frame members or door-posts, 8k the track beam, and 9 the track carried on the track beam and upon which the door is hung Jfor lateral movement from the closed Specification of Letters Patent.

position shown in Figure 2 to the partially open or retracted positionI in Figure 3, and for the usual longitudinal movement clear of and away from the doorway opening to one side of it.

The hanger proper is mounted on the door and comprises an attaching bracket portion 10 preferably, though not necessarily, substantially co-extensive with the upper end of said door to which it is attached, and a hood portion 11 in which is carried in spaced relation the rollers 12, 12, whose trunnions 13 are received in alined bearings provided in the side walls of the hood, one of which may be slotted as at 14 to permit the ready insertion of the roller into the hood. lin the preferred construction the hanger proper virtually serves as an extension of the door so as to fully close the door opening.

As more clearly shown in Figures 2, 3 and 4, the track preferably comprises the attaching portion 9a depending from the track beam 8 and has integral with it the horizontal track portion 15 along which the rollers 11 are designed to travel when the hood is positioned to extend into the clearance 16, which is provided between the track portion 15 and track-beam 8. Inasmuch as this track portion extends across the doorway opening and well to one side of it as is illustrated in Figure 1, it will be obvious, in view of the foregoing description, that with the door in the position shown in Figure 3, longitudinal movement of the door to clear the doorway opening is permitted.

The numeral 17 designates a roller carried by the track portion 15 in a manner to have its axis disposed at right angles to the axis of the roller 12, and are so located with reference to each other that when the door occupies a position either confronting or in the doorway opening, lateral movement j may be given the door to close it as in Figure 2 or it may be moved to partially open position as disclosed in Figure 3.

In the preferred construction, the horizontal track portion is formed with a slot and underneath this slot l provide a casting or housing 18 detachably secured to the under face of the track and provided with` bearings to receive the trunnions of the roller 17. The latter is formed with a' convex periphery which projects slightly above the plane of the track proper to present a portion of its peripheral face of curvature, which inclines from said plane, to

the roller l2 the door is moved longitudinally to confront the opening. When the door is positionedA in the opening, the.

roller l2 rests upon the roller 17 permitting lateral movement of the door to take up the position shown in Figure 2, and from thence-.tothe position shown in Figure 3. Either side wall of the hood 1l cop- K erates with the track to limit the outward movement of the door, and if desired the door may be provided with a flange 6a adapted to take against door frame membersVV in order to limit movement of the door.

From the foregoing, the essential features.,y

Vdesire to secure'by LettersrPatent, is the following V1V. In a car having a doorway opening, the combination with a door for said opening,

Vof a door ltrack having a substantially horizontal portion provided with a movable element adjacent said opening and projecting slightlyV above the'plane of said track portion, and a hanger on said door having a second movable element adapted for longitudinal movement along the said track portionV to bring the `door across said opening andfor lateral movement Vonthe iirst .element to bring the door into the said openinfr. Y

Y In a deviceofsubstant-ially the character described the vcombination of a door track having a substantially horizontal por- ,v tion,l a roller 'element carried by said portion and having an, inclinedperipheral pori tionrprojecti'ng ,slightlyV above the plane of said portion,fand a hanger provided with a second roller element disposed with reference to both said portions to travel in one direction on one of said portions and in another direction onthe other said portion.

3. In a car having a doorway opening and a doorway frame, a door for said opening,

Uopies of this patent. may. be obtained for a door track mounted on the frame above said door and having a substantially horizontal portion disposed beneath a frame member, there being a clearance between said portion and said frame member, a

Vlia-nger on said door having a hood project- Ving into said clearance, and cooperating antiy friction roller elements carried by said hood and said track portion for operative movement in said clearance.

4. In a device of the character described, the combination of a fixed track membei, a door hanger member movable therealong; and an anti-friction element carried by each of said members and disposed with reference to each other so that the anti-friction element of the movable member has movement in one direction along the track and in another direction on the anti-friction element of the fixed member, substantially as and for the purpose set forth.Y

5. In a car having a doorway frame and opening, a door for closing said opening, a door track supporting the door for longitudinal movement into a substantially parallel position opposite said opening, said door havingqan. upper projecting portion, and means whereby thel door has lateral movement into the. opening to close it comprising related co-acting anti-friction elements operatively disposed between the track and said upper projecting portion, substantially as and forl the purpose set forth.

6. In a car having a doorway .frame and opening, a door track extending longitudinally of thecar and supporting the door for Y lateral movement to clear the doorway opening and for longitudinal.l movement` to uncover said opening, said door being provided with an. upperprojecting portion, and means whereby the4 door is supported from the track for -free longitudinal movement, said means,v comprisingv co-active anti-friction elements disposed with reference to the track, andl said upper portion and each other whereby the door has lateral movement relativelyV of the track.

In testimony Vwhereof I have hereunto signed my naine in the presence of two subscribing witnesses.
